The AirTAC GFR600C25MLC1TK AirTAC Filter Regulator NPT1 is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600C25MLC1TK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 1 in NPT port, a 40 um standard filter element, a manual drain on the bowl, a low-pressure regulator type, a round pressure gauge scaled in MPa, and a built-in reverse (check) valve. The mounting bracket is included. The aluminium alloy bowl suits the largest frame in the range, and the unit works at up to 1.0 MPa (145 psi) inlet pressure in a -5 to 70 C (non-freezing) environment.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and PT, G or NPT threads. Drain, filter grade, gauge style and scale, regulator type and check-valve options let you match the unit to the circuit. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeding a workshop pneumatic press: the 40 um element strips water and pipe scale from the shop-air drop, the regulator sets the working pressure the press cylinders see, and the check valve holds the setting if upstream supply dips.
Protecting a valve-and-actuator manifold that runs below standard plant pressure: the low-pressure regulator type trims the supply to the circuit's working band while the filter keeps debris out of the valve seats.
Supplying air to conveyor gates and stopper cylinders on a packaging line: the filter-regulator gives one clean, set pressure point for the whole gate group, with the 1 in NPT port matching a main distribution leg.
Size 600 with a 1 in port is the largest step in the GFR range; step down to 400, 300 or 200 when your line flow and porting allow a smaller frame. Drain choice matters: this unit has a manual drain, so an operator or a scheduled routine drains the bowl, whereas automatic and differential-pressure drains are available on other variants. The 40 um element is the standard grade; a 5 um element (code W) is offered where finer filtration is needed. The round MPa gauge is fitted here; embedded square gauges and psi or bar scales are alternatives. Thread is NPT on this model, with PT (standard) and G available to order. The low-pressure regulator type suits circuits that run below standard supply pressure; the exact regulation range for this type is not published, so confirm it with us. Flow is published as curves, not a single rating, so ask us to check the curve against your application before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a number here. Tell us your line flow and pressure and we will confirm the sizing from the datasheet curve on request before you order.
The manual drain means the bowl is emptied by hand or on a scheduled routine instead of automatically, which suits installations that are checked regularly. The low-pressure regulator type is the variant intended for circuits running below standard supply pressure; its exact regulation range is not published, so confirm it with us. This unit also carries a round MPa gauge, a check valve, a 40 um element and a 1 in NPT port.
